In the late 1940s, Richard Feynman invented a visual tool for simplifying particle calculations that forever changed theoretical physics.
A new experiment confirms the existence of “superionic ice,” a bizarre form of water that might comprise the bulk of giant icy planets throughout the universe.
Mathematicians have found that materials conduct electricity when electrons follow a universal mathematical pattern.
The sun radiates far more high-frequency light than expected, raising questions about unknown features of the sun’s magnetic field and the possibility of even more exotic physics.
The stunning emergence of a new type of superconductivity with the mere twist of a carbon sheet has left physicists giddy, and its discoverer nearly overwhelmed.
A strange glow coming from the Milky Way’s center was thought to be due to ordinary pulsars. But a new look at a years-old study shows that dark matter might still be responsible.
Jim Gunn shaped the theory of the evolution of the cosmos before building cameras and spectrographs for major observatories like the Hubble Space Telescope.
